It's been 4 years since the last work... In response to the fervent requests of our users, the fully ripe fundoshi dancers are back in 2020!! Unfortunately, the Tokyo Olympics have been postponed, but the extremely vulgar festival of ass-shaking dance is about to begin!! The fundoshi digs vertically into the mansuji, and the crotch and anus are exposed, and the hips are twisted in a trance-like state, dancing nonstop in a frenzy of madness!! Don't think, just feel, 100 fully ripe fundoshi dancers, 8 hours forever!!
